Foods That Trigger Fat Storage

It's hard enough for your body to make use of nutrients from a diet high in fat and sugar. Now a study published in the Federation of American Societies for Experimental Biology Journal reports that fatty and sugary foods stimulate the kappa opioid receptor which promotes the storage of body fat. This discovery came out of an experiment where lab mice that had this receptor switched off remained lean despite consuming a high-fat/high-sugar diet for 16 weeks.

The Bigger Picture: According to this study, long-term consumption of calorie dense, fat-filled foods puts a double-whammy on your metabolism. As difficult as these foods are to process to begin with, the metabolic challenge is raised considerably higher due to the fact that your body has been turned into a fat-storing machine. It's something to keep in mind when you're tempted to go back for seconds.
